ABSTRAK: Pendidikan memiliki peran penting untuk mengembangkan segala potensi yang dimiliki siswa baik secara intelektual, spiritual, dan moral. Namun,siswa masih sering mendapatkan hasil pembelajaran yang rendah, terkhusus pada materi karya ilmiah. Tujuan diadakannya penelitian ini yaitu utuk meningkatkan keaktifan dan hasil belajar siswa melalui model problem based learning dengan pendekatan TaRL. Penelitian dilaksanakan dalam dua siklus dengan siswa sebanyak 37 siswa di kelas XI 9. Pengumpulan data dilakukan melalui observasi keaktifan, hasil belajar siswa, dan dokumentasi kegiatan pembelajaran. Dalam hasil penelitian menunjukkan bahwa siswa kelas XI 9 memiliki kekatifan dan hasil belajar yang rendah dengan rata-rata nilai Hasil penelitian menunjukkan bahwa pada siklus pertama, keaktifan dan hasil belajar siswa masih rendah 64,00. Kemudian diterapkan Kembali siklus dua dengan perbaikan pendalaman materi, barulah terdapat peningkatan yang signifikan dengan hasil rata-rata 82,11. Hal tersebut didukung dengan hasil uji-t yaitu nilai signifikansi 0,000 (p < 0,05). Sehingga dapat disimpulkan, penerapan model PBL dengan pendekatan TaRL dalam upaya meningkatkan keaktifan dan hasil belajar siswa terbukti berhasil dan dapat digunakan sebagai referensi dalam meningkatkan keaktifan dan hasil belajar siswa.

However, students still often get low learning outcomes, especially in scientific work material. The purpose of this study is to improve student activity and learning outcomes through the problem based learning model with the TaRL approach. The study was conducted in two cycles with 37 students in class XI 9. Data collection was carried out through observation of activity, student learning outcomes, and documentation of learning activities. The results of the study showed that students in class XI 9 had low activity and learning outcomes with an average value of The results of the study showed that in the first cycle, student activity and learning outcomes were still low at 64.00. Then the second cycle was re-applied with improvements in the depth of the material, only then was there a significant increase with an average result of 82.11. This is supported by the results of the t-test, namely a significance value of 0.000 (p <0.05). So it can be concluded that the application of the PBL model with the TaRL approach in an effort to improve student activity and learning outcomes has proven successful and can be used as a reference in improving student activity and learning outcomes.
